memory: Tier-3 store scrubbed clean (#368) + marker repro queued

Operator ruled full memory scrub both sides. Our memory.db wiped to 0
chunks, :8392 restarted born-empty (no backup, direct go); Sindra
pristine-baseline note marked obsolete. Marker repro (rhodochrosite,
fresh Sindra session) queued for after both scrubs confirmed; personal
is b125; current Lofn chunks are the feedback loop, mis-write unproven.
